CURTAIN-RING.

SPECIFICATION forming part of Letters Patent No. 763,691, dated June 28, 1904.

' Application filed October 17, 1903. Serial No. 1'77A20. (No model.)

To (bi/Z 1071,0172 it rnrtg concern:

Be it known that I, ALBERT L. PARKER, a citizen of the United States, residing at Rome, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Curtain-Rings, of which the following is a specification.

This invention relates to rings for curtainpoles or other analogous articles, and aims to provide certain improvements therein.

In the operation of forming a curtain-ring a brass (or other metal) strip is simultaneously drawn into tubular form and curved into a spiral. Suitable lengths are then sawed off and the ends of each length united to form .a ring, an eyelet being subsequently attached thereto.

It has heretofore been common to braze or solder the ends together; but this has been comparatively diflicult and expensive and has resulted in a weak and unsubstantial structure. To obviate this, it has been proposed to stamp up an eyelet from a metal blank and subsequently bend the blank into tubular form and then insert it in the ends of the ring with the eyelet projecting therefrom in position for use, the ends of the ring being riveted to the sleeve by bending portions thereof into a hole formed in the inner side of the latter. The principal objections to this form of ring have been the weakness of the eyelet (due to its being formed of a single piece of metal which is necessarily quite thin) and the cost of finishing the ring, it being necessary to bufi each ring by hand. A By my invention 1 provide a ring in which these disadvantages are obviated. In practicing my invention I first form a complete ring without any projecting parts or large depressions, so that it can be burnished in a lathe, thus saving approximately two-thirds of the cost of finishing, and after the burnishing operation is completed the eyelet is attached thereto, (which eyelet may be of any desired strength) and the ring is then ready for use without further manipulation.

Referring to the drawings, which illustrate my invention, Figure 1 is an elevation of a complete ring. Fig. 2 is a sectional view, on an enlarged scale, showing the method of attaching the ends of the ring. Fig. 3 is an ele- 'burnishing-tool.

vation and cross-section of the tubular plug or sleeve. Fig. 4: is a fragmentary view of the outer side of the ring. Fig. 5 is a similar view of the inner side thereof, and Fig. 6 is a view showing the parts of the eyelet detached.

Referring to the drawings, let A designate the ring, made usually of brass, having abutting ends a and 7).

B is a tubular plug or sleeve, preferably comprising a piece of metal drawn into tubular form and extending in the arc of a circle corresponding to that of the ring A. The plug B is designed to fit closely within the ring, as best shown in Fig. a. It is formed upon its inner side with a depression or hole 0, which is designed to receive the four corners of the ends a and b of the ring. hen the plug is adjusted in place within the ring, these corners are forced down into the hole 0 by a suitable punch or othertool, thus riveting the ends of the ring to the plug, as shown at 0, Figs. 2 and 5, and forming a strong and durable bond between the ends, so that they shall not spring out of contact in use. The holecshould be comparatively small, so as not to present a depression of sufficient size to receive the The ring is now placed in a burnishing-lathe and dressed in the usual manner, which operation is rendered possible by the fact that the ring has no large depressions and as yet no projecting parts, which would prevent the use of the burnishing-tool.

After the ring is burnished it is fitted with an eyelet O, which may be constructed in any suitable way, that showncomprising two apertured eyelet portions 6 and f, which have oppositely-bent legs a f, respectively, which are separately inserted into the ring through openings d and 9, formed in the plug and ring, respectively. When the portions 0 and f have been adjusted in position, they are united by a headed gromet it, which is passed into the coinciding openings of the portions 0 and f, its straight or shank end being turned or swaged, as shown in Fig- 2, thereby riveting the portions of the eyelet together and forming a strong and durable member from which to suspend the curtain or other hanging in use.

The ring provided by my invention may be much more cheaply manufactured, has a better appearance, and 1s of much stronger and more lasting construction than those now in I claim as my invention the following-defined novel features, substantially as hereinbefore specified, namely:

1. A curtain-ring having tubular ends, a plug fitting within said ends, and having an opening on its outer side, and an eyelet adapted to fit within said opening, and to engage said plug, said ring having a substantially continuous and uniform exterior surface without material depressions or projections prior to the attachment of the eyelet, whereby it presents substantially no inequalities to the tool during the burnishing operation.

2. A curtain-ring having tubular ends, a tubular plug fitting within said ends having a depression on its inner side within which portions of said ring are bent to hold the ends thereof together, and said plug having an opening on its outer side, and said ring having a coinciding opening, and an eyelet fitting through said openings and engaging said plug, the openings in said ring being of small size and the exterior of said ring otherwise substantially continuous, so as to permit the passage of the burnishing-tool over it, prior to the attachment of the eyelet.

3. A curtain-ring having tubular ends, a tubular plug fitting in such ends and extending wholly within the periphery of said ring, said ring having an opening for the reception of an eyelet, and having a substantially continuous and uniform exterior without material depressions or projections prior to the attachment thereof, and an eyelet fitting within said opening, and held in place therein.

In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
